Luxurious City bar is demolished (9)
I believe the answer is:
sybaritic
'luxurious' is the definition.
(I know that luxurious can be written as sybaritic)
'city bar is demolished' is the wordplay.
'demolished' indicates an anagram.
'city'+'bar'+'is'='citybaris'
'citybaris' anagrammed gives 'SYBARITIC'.
(Other definitions for sybaritic that I've seen before include "Hedonistic" , "Devoted to luxury" , "Affording, enjoying, luxury" .)
